AMT gray goo vs. new plastic?

[iBorg]

I'm working on a Garlits RE dragster. I started this before the current reissue. One thing that has always maddened me about MPC's dragsters in general is how poorly the body fits the frame. I'm trying to narrow the body. The gray goo doesn't seem to be making as strong of a joint as I'd like. Does the newer plastic make a stronger bond?

Thanks for the wisdom.

I have noticed I ever the years,  that the are many varieties of styrene. Not all are created equal.

Mark,

I am building a AMT/ERTL /MPC Mustang Mach 1.The Instructions quote:" We recommend using liquid polystyrene cement it forms a "weld" between two surfaces" I have put together the engine and the 2 front seats with no problems. 

Hope this helps

others may have different results, but I prefer the new plastic when slicing and dicing.  I use a razor saw and flat file to fit - edges are smoother with the new plastic - straight cuts glue together better.  I've been using Tamiya Super Thin or Plastruct Bondene to "weld" the pieces back together.  The new plastic is definitely harder than the old gray gooey stuff. I've "replaced" a couple of kits because the new plastic glues better - build the new, gray plastic becomes the parts donor.

For building,this is one of those cases where moern is better.  Plain, uncoloured styrene seemed to take glue better.  I'm chopping the top on an oler AMT Mercury, and even with the Tamiya extra thin, getting the chopped roof to stay together is proving to be a challenge.
